STARTING DEVICE FOR MOTOR-VEHICLES.

To all whom, it may concern 7 Be it known that I, EMERSON of Chicago, inthe'countyof Cook and State of Illinois, have invented certain new anduseful Improvements in Starting Devices for Motor-Vehicles; and Idohereby declare that the following is a full, clear, and exactdescription thereof,referen ce being had to ters of reference markedthereon, which form a part of this specification.

This invention relatest'o improvements in starting devices for explosiveor internal combustion engines, and more particularly to startingdevices that are operated by an electric motor and are adapted for usein connection with'the engines of automobiles V and like power drivenvehicles.

Among the objects of my invention'are to provide an electric startingdevice that is compact and simple in construction and certain inoperation, that may be easily con trolled by the operator, and isadapted to be .applied or attached to engines of the kinds or typesheretofore in common use, without requiring anychanges to be made insuch engines. f Q

My invention herein described and shown as applied to the engine of thattype of motor vehicle known as the'Ford although it may be applied toother. makes of motor vehicles having similar features. of construction.'l

My invention consists therefore in the matters hereinafter set forth andmore specificallv pointed out in the appended claims.

As illustrated in the accompanying drawings, Figure. 1 is a top planView of the transmission cover and starting device; Fig. 2 is a view inlongitudinal section of a transmission cover or casing and of mystarting device mounted thereon; Fig. 3 is an, en larged detail viewtaken on line 33 of Fig. 2; and Fig. .tis a detail view showing a formof set screw employed in securing-the starting devicje in place. I e

and forming" a rearward extension of the crank case of the motor, and anupper port1on or cover l2.- Sald cover 12 is removably attached to thelower casing member substantially in a horizontal plane passing throughthe longitudinal aXis of the casing. Thejoints between the margins ofthe cover the accompanying drawings, and to the let- 12 and the lowercasing member 11 are formed by means of flanges 11 and 12 on said parts,through which extend bolts or screws '13. r In its larger, forward part17, which covers thefly-wheel 15, the cover 12 is semi-circular in form,and the walls of said cover are tapered orinclined from its larger, orforward, to its smaller rear end. -The gear casing 10 issituatedimmediately beneath the floor 1 1 of thefcar and forward of thedrivers seat, The fly-wheel 15 is mounted upon the crank shaft 16 in theusual manner. f g

In the top of the cover 12, the inclined or tapered-portion thereof ismade flat, so as to form a flat, inclined wall-section 18, ex-

tending from the rear margin of the en! larged forward part 17 of thecover rearwardly and downwardly to the rear end thereof. In this flatwall-section 18 is provided an opening 19, which forms a handhole, bywhich access may be had to the transmission gearing. This opening 19 istapered to conformto the shape of thecover 12, as seen in plan view;that is to say, its lateral margins converge. or taper from front torear and its lower or rear margin being shorter than its forward orupper margin. 'Thls openln'g or hand-hole is' situated below a portionof the floor of the vehicle, ordinarily serving as a foot rest for thedriver, which is usually made removable for the purpose of gainingaccess to the mechanism immediately below the same.

In the usual construction of vehicles having a gear-casing made asillustrated, this hand-hole 19 is covered bya flat plate ofsubstantially the same shape as that of the hole, arranged to overlap atitsmargins,

and secured to the cover by means of a plurality of cap screws, and insuch manner that it can be easily removed by a conven ient tool, so thataccess may be had therethrough to the mechanism within the trans-,mission casing, for the purpose of repairs or adjustment.

A starting'device made in accordance with my invention is provided witha base or supporting frame member, having the same general dimensions asthat of the hand-hole plate, and which may be substituted for suchhand-hole plate, as a cover or closure for the hand-hole, thus making itpossible to attach the starting device to a vehicle already in use, andto equip new vehicles with starting devices without necessitating adeparture from the standard design or construction of the vehicle.

Referring now to the features of construction of the starting device,the same embodies parts as follows: The base plate or supporting member20 is adapted to fit at its margins the edges of the opening orhand-hole 19, said plate having the same shape as that of the handhole,and being adapted to engage in overlapping relation the margins of saidhand-hole. A plurality of cap screws 21 extend through holes formed inthe marginal portions of the base plate 20, and engage screw-threadedapertures in the margins of the cover 12, which surrounds said handhole.

Integral with the base plate 20 at the forward part of the same is ahollow casing 22 located at the central portion thereof, the interior ofsaid casing opening directly into the transmission casing and forming ineffect a portion of the same. The casing 22 projects upwardly andrearwardly from the base plate and is tapered as it approaches its upperextremity where it assumes the shape of a cylindric tube. The upper partof said casing 22 is designed to extend through an aperture 146 formedin the floor 14; of the vehicle and within convenient reach of theoperators foot. This casing-supports an endwise movable operatingplunger 23 hereinafter to be described in detail.

Projecting downwardly from under the surface of the base plate 20 is abearing, lug or arm 21, preferably formed integral with said plate andlocated at the forward end thereof immediately adjacent to the forwardwall of the plunger casing 22. The upper portion of the bearing arm 2 1is perpendicular to the base plate and forms a shoulder 24: adapted toengage the adjacent margin of the opening or hand-hole 19 for thepurpose of aiding in the proper placement of the base plate. The lowerportion of the bearing arm is inclined relatively to its upper portion,and is at right angles to the axis of the driving shaft. Through saidlower portion of the bearing arm extends a horizontal bore, forming abearing for the forward end of the shaft 26 of the starting mechanism.The bearing arm is shown as provided with a bushing 25. In horizontalalinement with the bearing formed by the arm 24:, and rearwardlythereof, is another bearing 27. This bearing has the form of a shorttube or sleeve, made integral with the base plate, and extendinghorizontally through said base plate obliquely with relation to theplane of said plate. The forward end of the bearing-sleeve 27 terminatesat the lower end of the rear wall of the plunger casing 22, and isjoined integrally to the lower margin of said rear wall. Thisbearing-sleeve 27 is also provided with a bushing 28, and supports therear end of the starter shaft 26; it being noted that the bearingaperture in said sleeve forms an opening in the base plate 20, throughwhich the starter shaft extends in passing from the interior of thetransmission casing to the exterior thereof.

At the rear portion of the base plate 20 is provided a motor supportingframe 30, comprising two laterally and upwardly inclined webs 31,preferably formed integral with said base plate and between which ismount ed the electric motor The rear portions of the webs 31 projectrearv-Jardly beyond the rear end of the base plate 20, and at their rearextremities and forward extremities are provided with lugs 33 adapted toengage the lugs or arms 31 on the sides of the motor 32. A bolt 35extends through each pair of engaging lugs whereby the motor is rigidlysecured in place. The motor is mounted between the webs '31 in such manner that the armature shaft is in longitudinal alinement with the shafts26. A depression 20 is formed in the base plate 20 to give room for theforward end of the motor. The armature shaft projects from the motor atits forward end and is directly connected in driving engagement with theshaft 26 by means of a shaft coupling 36 adapted to afford relativeendwise movement between the starter shaft and armature shaft. Saidcoupling 36 comprises a bifurcated member 36 mounted upon the armatureshaft, and a tongue member 36 adapted to fit loosely within the spacebetween the arms of the said bifurcated memher. The purpose of providingsuch a joint between the motor and starter shafts is to permit endwisemovement of said shaft without disconnecting the same from the shaft.

At the forward end of the shaft 26, and adjacent to the fly-wheel 15, isrigidly mounted a spur gear-wheel or pinion 37, adapted to rotate withthe shaft 32 and to move endwise therewith. This pinion is adapted tomesh with an annular gear or ring 38 provided with gear teeth, andrigidly secured to the rear surface of the flywheel, adjacent to theperiphery thereof. Said ring is provided with a plurality of radiallyextending fingers or arms 38, adapted to extend over and engage theperipheral surface of said fly-wheel, and there by acting to afford theproper concentric position of the ring 38 upon the fly-wheel.

The said ring is secured to the fly-wheel by means of screws 39extending through the located intermediate the ends ofsaid shaft.

and between the bearings 24 and 27. The

collar '40is provided withan annular groove 41' within whichislocated aU-shaped yoke member 42 which extends around the uppermost portionofsaid collar 40. Said yoke member 42 is provided with rigid, laterallyextending pins orlstuds 42 42 the axes of said pinsbeing horizontal inalinement with the axis of the shaft 26. member 42 has operativeconnection with a shifting lever 43. which has connection with the baseplate20." Said shifting, as shown, has the form of afbell crank lever,comprising two arms 44 and arranged substan- The tially at right anglesto each other. arm 44 of the lever 43 is U-shaped and embraces the yokemember 42, the ends of said U-shaped arm 44 being bifurcated to formslots 44, 44 adapted toreceive the pins 42 of said yoke member 42. Thelever 43 is pivoted atthe intersectionof the arms 44 and 45 thereof to alug 43 integral with the baseplate and located at the base of theforward wall of the plunger casing 22. The arm45. of the lever43 extendsupwardly and rearwardly into. the plunger casing and is provided at itsend with a rounded head 45 adapted to have constant sliding contact withthe plunger 23. The plunger 23 comprises two pivotally connected members46 and47, the member 46 being cylindric in form and adapted to fit andslide endwise within'the upper tubular end portion of the plungercasing. The other member 47 of the plunger is pivotally connected by ahorizontal, transverse pivot to the lower or in ner end of the member 46and projects into the space formed within the lower part of the plungercasing. Said member 47 is preferably in the, form of a block,rectangular incross-section, and provided at-its lower or swinging endwith an oblique or cam sur face 48, said cam surface being inclined tothe :path of movement of the plunger and sloping from the upper surfaceof the memher to thelower surface. 'At the point of intersection of theoblique end surface and theupper surface of. the member 47, is provideda flat arm" or projection 47 extending 7 from the lower end of saidmember adjacent tothe top or forward wall of the casing22; the undersurface of said projection'47 and the cam' surface of the member 47being joined by a slightly curved surface or fillet. The said obliquesurface 48,}the un- The yoke der surface of the projection 47 and thelower or downwardly facing surface of the member 47 form contact or camsurfaces for the arm 45, as will hereinafter be'pointed out. 1

Referring further to the cylindricmem ber 46 of the plunger, the sameprojects at its upper end beyond or outside of 'the plunger casing andis provided at such upper end with a fiat head '46 adapted to receivethe pressure of the operators foot in the operation of the startingdevice. Between this head 46 and the upper end surface of the plungercasing is mounted a coiled spring 49, which surrounds the end portion ofthe plunger member 46, said springacting to force the plunger outwardlyor'upwardly when the pressure upon the plunger is released.

At the base of the front wall of the plum ger casing 22 is provided aset screw 50 which has screw-threadedengagement with said casingimmediately above the plunger member 47. This set screw projectsthroughthewall of the casing and engages the up per surface of said member andof the projection 47 thereof. This set screw is adapted to be adjustedinwardly and outwardly and forms an adjustable stop which holds themember 47 from swinging upwardly about its point of pivotal connectionwith the cylindric member 46, and acts to maintain said member in thedesired position of adjustment, there being provided a lock nut 51 uponthe stem ofsaid set screw for the purpose of securing the set screw frommovement whenthe desired adjustment has been obtained.

The head 45 of the lever arm 45 is adapted to constantly coact" with theplunger member 47 and, in orderto insure. the positive contact of thesemembers, a coiled spring 52 is employed, which is secured at one end tothe arm 44 of the lever 43, immediately below its point of pivotal connection with the casing, and extends in a horizontal directionsubstantially parallel with the shaft 26, and is connected at its otherend to the opposite sideof the-plunger casing adjacent to the inner endof the bearing 27. This spring performs a double function, namely tomaintain the arm 45 in constant contact with the plunger and to withdrawthe bevel gear 37 from the annular gear upon the fly-wheel, when thepressure upon the plunger 23 is released.

'The operation of the members of the starting device thus far describedmay be described as follows: As shown in full lines in Fig. 2, themembers of the device are in their non-operative position, the shaftbeing shifted in a direction away from the fly-wheel so that the pinion37 is disengaged from the annular gear 38 ofsaid fly-wheel. The plunger23 is at this time at the outer plunger.

extremity of its movement, being moved and maintained in that positionby the expansive action of the coiled spring 49. The lever 4:8, by meansof which the movement of the plunger is transmitted to the shaft, is atthis time held by the spring 52 in position with its head 45 on thelever arm l?) in contact with the forward portion of the oblique endsurface l8 of the plunger member 47, and adjacent to the projection 4:7of said plunger. The several members are now in position to be actuatedfor the purpose of throwing the said gears into mesh. This operation isaccomplished by exerting a downward pressure upon the head 1-6 of theplunger 23, whereby said plunger is forced downwardly. This movement ofthe plunger acts to oscillate the lever 4-3, by reason of the contact ofsaid lever arm l5 with the oblique surface l8 of the plunger member 4:7.The oscillatory movement of the lever is transmitted to the shaft 26through the medium of the U-shaped arm 5%, the yoke member 42 and collar40 acting to transform the oscillatory motion of the lever into a linearmotion acting to shift said shaft endwise to effect the intermeshing ofthe pinion 37 with the annular gear 38 of the fly-wheel. lVhen the gearsare fully engaged, the head 45 of the lever arm has passed beyond thelower margin of the oblique surface l8 and rests in contact with thelower longitudinal surface of the plunger member. This contact of thelever and the plunger acts to maintain the gears positively in mesh, byreason of the fact thatany force or jar exerted upon the shaft or othermembers of the device, with the exception of the plunger will benecessarily resisted by the contact of the head of the lever arm withthe flat horizontal surface of the plunger. The positive engagement ofthe starting device and the motor will be maintained so long as theoperator continues to exert downward pressure upon the The release ofthe pressure upon the plunger results in the immediate return of .heparts to their original positions, such return movement beingautomatically effected by means of the springs 49 and 50 in the mannerbefore stated.

in addition to the parts already described, I provide means for startingthe electric motor immediately after the gears have been. thrown intomesh. whereby the starter shaft is rotated and a rotative movementtransmitted to the fly-wheel and crank-shaft until the engine starts inoperation. This device consists of a switch 53 which is operated by themovement of the plunger and acts to close the circuit between the motorand a source of electrical energy, preferably in the form of a storagebattery carried by the vehicle. The switch 53 is mounted upon the underside or surface of the plunger casing and at the base of the tubularportion thereof, said switch consisting of a block in which are mountedtwo contact pieces 5 L, 5-l spaced apart and properly insulated fromeach other. These contact pieces 5- project in the direction of the endof the plunger and are further connected by suitable wires to terminalsor binding posts 55, to which are connected the conductors 56, leadingto the motor. From the under side of the plunger member 46, projects apin 5'7, which extends through a longitudinal slot 58 in the tubularportion of the plunger casing. This pin is so 1ocated upon the plungerthat when the latter is in its non-operative position, the pin is a adistance from the switch block 53, and when the plunger is pressedclownwardly the pin enters the space between the contact pieces andaffords electrical connection between said pieces, thus starting themotor. The relative location of the switch block and pin is such thatthe starting of the electric motor occurs immediately after the pinionon the starter shaft has been thrown into engagement with the annulargear 38 on the fly-wheel. The power of the motor is positivelytransmitted to the shaft 26 by means of the sliding shaft connection,which permits the shaft to be shifted enclwise without interfering withsaid positive transmission of rotary motion from the motor to the shaft.

It is to be understood that a starting clevice made in accordance withthe features herein set forth is adapted to be attached to any form ofmotor vehicle having a flywheel and. gear casing arranged in the generalrelation shown. It is to be further understood, however, that, althoughvehicles are designed and manufactured which are identical in everydetail of construction, it is nevertheless true that slight variationsfrequently exist, as for instance, in the case of new and old vehicles,due to greater wear on the parts of the latter than on the former, or inthe case of new vehicles a slight variation in the thickness of metalwhich would tend to vary the slightrelative positions of the moving andstationary parts in different vehicles. For this reason, it is necessaryto provide means whereby slight adjustment-s may be made in the startingdevice, so that the device may be attached to different vehicles of thesame make and any slight discrepancies overcome. It is for this reasonthat the set screw 50 is employed for adjusting the operative positionof the plunger member 47. The adjustment of the set screw 50 acts toswing the pivoted plunger member 47 relatively to the cylindric plungermember 46, and likewise to change the position of the lever d3, so as todetermine the endwise position of the shaft 26, when shifted toward thefly-wheel 15. By

Il2l V the use of said setscrew, therefore, any degree of, variation inthe relative positions of the coacting parts is overcome and the properengagement of the gearing is assured. Furthermore, to insure the properplacementof the base plate upon the transmission cover 12, I make thebolt holes, as shown at 60, Fig. 2, elongated in-the direction of thecenter line of the base plate 20, thereby permitting said base plate tobe adjusted longitudinally in order to compensate for any slightvariations in the dimensions between difierent vehicles to which mydevice is applied.

In attaching my starting device to a particular vehicle having a gearcasing made as illustratechth'e annular gear Wheel 38 is secured tothefly-wheel in the manner before stated, the fingers-or projections 38acting to properly locate the gear wheel in concentric relation to thefly-wheel. The handhole plate usually employed to close the opening 18in the gear-case cover, is removed and the base plate of the startingdevice fitted upon the gear casing in the same position as the removedhand-hole plate. The startingdevice is then adjusted, if necessary, bymeans of the elongated bolt holes andthe set screw 50, so as to bringthe pinion 37-accurately in position in relation to the annular gear 88of the fly wheel. For the purpose of retaining the starting devicerigidly in position after being properly placed, I provide in the baseplate 20 a set screw .61 (Fig. 4) provided 'with' a screwrthreadedportion 61 adjacent to its head and a projection or dowel pinandtightened; the dowel pin engaging the hole in the gear-case. In thismanner liability of longitudinal movement of the base plate, by reasonof the elongated form of the bolt hole employed, is prevented, and

furthermore the, setscrew 61 acts'to determine the proper positionof thestartingdevice in replacing the same, whenever the starting device isremoved for the purpose of giving access to the interior of the gearcasing or for making repairs.

A starting device, constructed in accord-' ance with my invention andadapted to be applied to a motor in the manner set forth,

possesses a number o'f'advantageous features, as regards location,manner of attachment, and operation. 'The device is immediately adjacentto'the point wherethe power is to be applied, and of easy access fromthe drivers seat; it is located upon the upper surface of thegear-casing and close to the crank shaft and transmission gears, and forthat reason is not subject to contact with dirt and grease that isordinarily present in the lower portion of the gear-casing. A furtherfeature of the device is the ease with which the device may be attachedto the vehicle, there being required no especially formed supports orattachments and no alteration in the mechanism of the engine. The devicebecomes in effect an integral part of the casing for the transmissiongear, and, in view of the fact that the movable parts of the de vice arelocated entirely within such casing, and the plunger-casingof the devicecommunicates directly with said gear-casing, the operative parts areadapted to receive lubricant introduced into the said casing in the samemanner as provided for the other portions of mechanism located withinsuch casing. No independent means of lubrication is therefore required,and no attention need be given to the oiling or lubrication of thedelVhile the device embodying my invention is particularly adapted foruse in connection with a Ford automobile, it is to be understood that itmay be variously modified in its details of construction withoutdeparting fromthe spirit of the invention. For these reasons, myinvention is not limited to the particular features of constructionshown and described, except so far as pointed out in theappended'claims.
